Brass or Stainless Steel Test Sieves: That Was Then, This Is Now

For this blog article, we will look at the use of brass for weaving the mesh of laboratory test sieves and how stainless steel has become a more efficient and cost-effective mesh material.

Construction Materials Testing: An Overview
Construction Materials Testing Resource

The term construction materials testing sounds like a catch-all term for analyzing everything from nails to doorknobs. However, for the civil engineering industry, it has come to mean the characterization of a handful of things by using specific test methods in a construction materials testing laboratory: concrete, aggregates, asphalt, and soils. This blog will take a high-altitude view of what construction materials are, the most important properties to test for, and the right equipment to get the job done.

Test Sieve Accuracy: Verification, Calibration, & Performance

Verification, calibration, and performance tests all contribute to the accuracy of test sieves. Understanding sieve accuracy will ensure you get the information you need out of your test sieves or screen trays.

Factoring in Flowability of Granular Materials: Sieving and Sizing

Test methods for dry granular materials must be built around the flowability of the material. No sampling, sizing, or handling method can be performed accurately or efficiently if it does not work in harmony with the material's flow properties.

Sieving and Screening Accessories for Better Testing

Particle sizing with test sieves is a hands-on process with many small, repetitive tasks that must be carried out properly. Selecting the right accessories for each job and using them correctly makes the work faster and easier, but it also significantly affects testing efficiency, accuracy, and repeatability. This article closely examines the tools that optimize test sieving procedures and ensure your sieves meet the requirements of standard test methods.

Laboratory Test Sieves: What You Should Know

Test sieves are simple devices, but they are still scientific instruments and the most cost-effective and widely used particle sizing and gradation testing method. This blog article will cover the accuracy verification of sieves, agitation and sieve shakers, accessories, and wet-wash sieves.

Choosing the Right Gilson Screen Shaker

Particle size gradation is the most often-performed test on aggregates, and effective characterization can’t move forward without it. Testing screens offer an efficient and cost-effective method for accurate size determinations of coarse materials. This blog post will help you select the right Gilson Screen Shaker for your testing applications.

Gilson Testing Screen Trays: Easy Maintenance for Optimum Accuracy & Maximum Life

Screen Trays are the heart of all Gilson Testing Screen Shakers. In this blog post, we discuss how to get the most accurate results and extended life from your testing screen trays.

What is a Sieve? Make Sure You Choose the Right One

Quick, name the most widely used and cost-effective scientific instrument in your laboratory. Some possibilities come to mind, but our argument is for the ordinary test sieve. In this month’s blog post we discuss the purpose of sieves and how to select the right sieve to fit your particle sizing needs.

Coarse Aggregate Gradation: Test Sieves or Screen Trays?

Does the particle size analysis of coarse aggregates always require a testing screen with large screen trays? In a situation where larger testing equipment is not available, there may still be ways to get the job done. Using conventional round test sieves for large particle sizes is less efficient, but still acceptable if done properly. We discuss test requirements, sieve capacities, and tips to help with equipment selection.
